Misuse of sulphonylureas, rather than an insulinoma, may be the cause of spontaneous hypoglycaemiaBMJ 1997; 314 doi: https://doi.org/10.1136/bmj.314.7079.0e (Published 15 February 1997) Cite this as: BMJ 1997;314:e
This week's lesson of the week describes a woman with worsening spontaneous hypoglycaemic episodes who underwent exploratory laparotomy for a possible insulinoma (p 496). No tumour was found, and a serum sample taken during an earlier hypoglycaemic episode was reanalysed for sulphonylureas and showed a high concentration of glibencamide. She then admitted taking a relative's tablets. The authors recommend that insulinomas should not be diagnosed unless sulphonylurea misuse has been excluded.
